![]() At wavelengths shorter than 450 nm, silver's reflectivity is inferior to that of aluminium and drops to zero near 310 nm. Protected silver has greater optical reflectivity than aluminium at all wavelengths longer than ~450 nm. Silver has a brilliant, white, metallic luster that can take a high polish, and which is so characteristic that the name of the metal itself has become a colour name. This observation explains the low hardness and high ductility of single crystals of silver. Unlike metals with incomplete d-shells, metallic bonds in silver are lacking a covalent character and are relatively weak. Silver crystallizes in a face-centered cubic lattice with bulk coordination number 12, where only the single 5s electron is delocalized, similarly to copper and gold. Silver is a relatively soft and extremely ductile and malleable transition metal, though it is slightly less malleable than gold. ![]() This distinctive electron configuration, with a single electron in the highest occupied s subshell over a filled d subshell, accounts for many of the singular properties of metallic silver. Its 47 electrons are arranged in the configuration 4d 105s 1, similarly to copper (3d 104s 1) and gold (4f 145d 106s 1) group 11 is one of the few groups in the d-block which has a completely consistent set of electron configurations. Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table: copper, and gold. Silver is extremely ductile, and can be drawn into a wire one atom wide. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants and microbiocides ( oligodynamic effect), added to bandages, wound-dressings, catheters, and other medical instruments. Its compounds are used in photographic and X-ray film. Other than in currency and as an investment medium ( coins and bullion), silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term " silverware"), in electrical contacts and conductors, in specialized mirrors, window coatings, in catalysis of chemical reactions, as a colorant in stained glass, and in specialized confectionery. As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Its purity is typically measured on a per-mille basis a 94%-pure alloy is described as "0.940 fine". Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Silver has long been valued as a precious metal. ![]() Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is a chemical element with the symbol Ag (from Latin argentum 'silver', derived from the Proto-Indo-European h₂erǵ 'shiny, white') and atomic number 47. ![]() These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s cine lens line-up for professional cinematographers and provides an exquisite feel to touch as well as sound effects, making photographers want to reach for it and play with it over and over again. Metal materials are also used in internal structures that slide with the operation ring for added robustness. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability, which improves the quality of the entire product. In addition, the smooth focus drive system designed around a quiet and fast stepping motor also makes the 24mm F3.5 DG DN | Contemporary a desirable choice for shooting video.Īll I series lenses have an all-metal construction. Together they make it possible to combine high optical performance with compactness. This includes high-precision, glass-molded aspherical elements created with advanced processing technology, and SLD glass and high refractive index glass elements. The lens features the latest optical design optimized for mirrorless systems. This helps create a close-up image of an in-focus subject with a blurred background, a technique that is very useful in a variety of settings. In addition to the attractive bokeh, it also gives photographers near-circular out-of-focus highlights, even at the edges of the frame. ![]() With a minimum focus distance of around 10cm and a maximum reproduction ratio of 1:2, it enables photographers to explore a subject more freely, from capturing distant landscapes to photographing close-ups of smaller objects. The high resolving power of the 24mm F3.5 DG DN | Contemporary covers the entire image from the center to the edges, which means photographers can rely on edge-to-edge sharpness at all apertures when shooting wide-angle scenes. With this as a base, SIGMA has given careful thought how photographers use and enjoy their lenses, including optical design, advanced functionality, build quality and the experience of picking up and using the lens, and with all of this carefully considered, the I series was born. SIGMA’s excellence in development and processing technologies has been built up since its founding in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision in 2012. Simultaneously, SIGMA is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of “taking pictures” when they choose to own a camera and lenses. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers. One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 24mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. ![]() The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve. ![]() That’s why there’s egg yolk in mayonnaise-the lecithin in the yolk emulsifies the oil and the vinegar together. It’s still made out of oil droplets dispersed in water, but the emulsifying molecules attached to each oil droplet let the droplets stay cozily mingled with the water instead of rising to the top. With the emulsifier encouraging them to intermingle, an emulsion can stay stable for a much longer time. So when it’s mixed in with oil and water, a lecithin molecule grabs on to an oil droplet with its fat-loving end, and with its water-loving part facing the water. It’s a large molecule with one part that’s attracted to oil, and another part that’s attracted to water. A common example is lecithin, which is found in egg yolks, soybeans, and other sources. But how can we keep it from coming apart after a few minutes? An emulsifier.Įmulsifiers are like kids who are friendly with the girls’ clique and the boys’ clique. This is an emulsion: a mixture in which small drops of one substance are dispersed throughout another substance. Or at least, it takes them a little longer to do so: long enough to pour a shaken vinaigrette onto a salad, but not long enough to store it in the fridge without needing to shake it up again next time. Forcibly whipping oil and water together will break the oil up into little droplets, which aren’t individually buoyant enough to push through the water and form a separate layer again. If you have a blender, or a good whisking arm, you can get them to play nice for a while. The two kinds of molecules have no way to cling together, so they stay in their separate areas, like middle schoolers at a dance. Water also clings to other kinds of molecules that have charged poles, like salt or alcohol, forming a solution.īut oil molecules have no positive or negative charge-they are non-polar-and so water is indifferent to them. Water molecules cling together, with the positive pole of one water molecule sticking to the negative pole of the next. Each molecule of water has two ends, one with a positive charge and one with a negative charge, and, just like in magnets, the opposite poles attract each other. Why don’t they mix? They’re different kinds of molecules. “Like girls and boys in the lunchroom,” the teacher said. It’s a truism we learn in elementary school. Get ready to impress at your next cocktail party. We’ll be sharing many of these fun words with you in this ongoing series, Word of the Week. Working at the intersection of food and science, we come across a LOT of scientific jargon and terminology, from chemical processes (see: nixtamalization), to physical phenomena, to species names (see: Aspergillus oryzae ). |
